INVALIDS BED.

Application led September 23, 1922. Serial No. 590,177.

To all whom t may coowern:

Be it known that I, WILLIAM A. MoCoL- Lonen, a citizen of the United States of America, and resident of Webster City, Hamilton County, Iowa, have invented a new and useful Invalids Bed, of which the following is a specification.

The object of this invention is to provide an improved invalids bed adapted to be manipulated and adjusted in many different ways to accommodate the patient and lto facilitate the work of those ministering to him, and particularly to provide means for raising the patient bodily from the bed, by mechanical means and Without unduly disturbing him, for the purpose of changing bed clothing and the like.

A further object of this invention is to provide improved means for adjusting a bed bottom vertically in a horizontal plane relative to the supporting frame.

With/these and other objects in view, my invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure 1 is a side elevation illustratinr my improvedbed. Figure 2 is a head end elevation of the same. Figure 3 is a plan of a portion of the bed bottom. Figure 4 is a sectional elevation substantially on the line 1-4 of Figure 1, on an enlarged scale. Figure 5 is a' detail section showing the means for adjustablv mounting a corner of the bed bottom relative to the frame. Figures 6 and 7 are elevations, at right angles to each other, of members employed in adjustably supporting the patient raising devices. Figure 8 is an elevation on an enlarged scale, partly xin section, of the standard attachment. Figure 9 is a section, on an enlarged scale, on the line 9-9 of Figure 2. Figure 10 is an elevation, partly in section, showing the attachment for supportinv a Weight to be applied tothe patients body, and Figure 11 is an elevation at right angles thereto, a portion being broken away to economize space.

In the construction of the bed as shown' the numerals 10, designate s aced head posts connected at their upper ens by a cross-bar 11, which may be integral with or separately formed and suitably connected to said posts; and the numerals 12 designate foot posts spaced apart and connected'similarly by a cross-bar 13. The numerals 14 designate side rails connecting the head and foot posts in pairs, the manner of their connection bemg hereinafter more fully described. The posts, cross-bars and side rails preferably are formed of channel bars, butmay be of other suitable members. The posts 10, 12 preferably are supported by casters 15.

The bed bottom is mounted between the side rails 14 and is composedhof three sections separately adj ustable, said sections comprising a pivoted head section A, a pivoted foot section B and a pivoted seat section C between the head and foot sections. Each section A, B, C is composed of spaced side bars 16, 17 which may Well be formed of angle. iron, connected by underlying brace members 18 of any desired number; andthe head and foot sections are in addition connected, as to their side bars 16, 17, by' end bars 19 (Figure 2) and by over-arching rods 20 at their outer ends. A series of coil springs 21 are attached at spaced intervals to each of the side bars 16 and 17 of the several bed sections A, B and C and a iiexible member 22,.such as a chain, is emplo ed to connect said springs and to form a exible and resilient bottom for the bed which is continuous from the outer end of the head section A, through the intermediate or seat section C, to the outer end of the foot section B. The chain 22 may be connected at one end to a spring 21 having a connection with one side bar 16, pass obliquely across to a spring having a connection with the opposite sidebar 17 and thence back and forth successively from one side bar to the other on oblique lines to the opposite end of the bed; and then be brought back on oppositely inclined lines, crossing the first mentioned portions of the chain at or near the median ine of the bed, until the initial end of the bed is reached.' The springs 21 may be hooked at one end into apertures in the side bars and at the other end into links of the chain 22. In this manner a very comfort-- able and uniformly yielding bed bottom is provided, which will yield at all points and fit itself to the body of the occupant in any position. If desired two separate sections of chain may be employed, each having connection successively with alternate springs on each side of the bed but in such staggered rrrangement that the chains cross on oblique ines.

If desired a vent opening may be formed in the central portion of the intermediate or .Iset section O, as shown in Figure 3. A

frame 23, in this instance rectan lar, is arranged in the plane of the side ars 16, 17 of the section C and interposed in the ,yielding bottom formed by the springs 21 and chain 22. Springs 24 are connected to the sides of the frame 23 and receive attachment of links of the chain or chains 22, such chain or chains extending, for the length of the frame, only from one side bar 16, 17 to an adjacent side of said frame 23, instead of extending entirely across the bed section, leaving an open space enclosed by said frame. Other springs 25 may be employed at ends of the frame 23 for connection to suitable adjacent ortions of the chain 22. The mattress an bed lclothing employed with the bed may be formed with openings registering with the opening of the frame 23, and a tubular member 26, formed of rubber or other suitable water-proof material, may be provided to extend from said frame to a receptacle such as 27 located beneath the bed. Thus provision is made whereby a bed-fast patient may vent without materially changing his position in the bed and without the use of an extraneous device such as a bed-pan, any suitable protection for the mattress and bed-clothing,

4such as rubber sheets, being provided if desired.

The inner ends of the side bars 16, 17 of the head section A are pivoted to thev side rails 14 of the bed frame by means of bolts 28; and the adjacent ends of the side bars 16,'17 of the intermediate section O are conjunctivel pivoted on said bolts. The opposite en s of the side bars of the seat section C are pivoted to inner end portions of the side bars 16, 17 respectively of the foot section B, by means of bolts or rivets 29. The head, seat and foot sections are thus arranged end to end within the space` enclosed by the side rails 14 and occupy the major portion of such space. The pivoted sections may at times occupy the same horizontal plane as the side rails 14, and may be adjusted to various inclined positions out of such plane.

The channels comprising the head posts l0 open inwardly toward the median line of thebed and the channeled cross-bar 11 connecting them preferably opens downwardly. The mechanism for operating the pivoted head section A^is quite similar to that illustrated and described in my companion application iiled October 27. 1921, Serial Number 510,779, and includes an operating shaft 30 journaled in the head posts within or somewhat below the crossar 11 and adapted to be rotated by means of a detachable hand crank such as 31. One or more spools or drums 32 are fixed to the shaft 30, anda cable 33 is fixed to and adapted to be wound on each of said spools Y Lesespa or drums. A rod or spindle 34 is mounted transversely of the bed beneath the shaft 30 and its ends project within the channeled posts 10. Each cable 33 passes beneath a roller or pulley 35 pivoted on the vrod or spindle 34, thence upwardly and over a roller or pulley 36 carried by the adjacent post 10, thence downwardly to a point of attachment to a bar 40 pivoted on the rod or spindle 34 adjacent the pulley 35. Thus the rod or spindle 34 is suspended and may be moved upwardly or downwardly by selective rotation of the shaft 30 in either direction. The projecting ends of the rod or spindle 34 carry pivoted rollers 37 within the channeled posts 10 and it is the functionv of said rollers, by contact with the walls of said channels, to minimize friction in the movement of said rod or spindle. Links 38, 39 are pivoted at their ends to end portions of the rodv or spindle 34 and have their opposite end portions adjustably pivoted to en portions of the side bars of the head section A, so that said head section is adjusted to any desired degree of inclination,

or allowed to rest in horizontal position, by

rotation of the shaft 30.

A ratchet wheel 41 (Figure 9) is fixed to A with a notch adapted for engagement withv a tooth of the ratchet wheel.

If desired the movable foot section B may be adjusted manually to inclined position, either independently of or conjunctively with adjustment of the head section A, and any desired means may be employed to prevent downward breaking of the joint between said foot section and the seat section O so that they may at times occupy the same inclined plane. lVhen so adjusted the free end of the foot section B may be supported by means of notched brace members 44 pivoted thereto and adapted to engage pins 45 carried by the side rails 14, (dotted lines Figure 1).

At times it is desirable to break upwardly the joint between the seat section C and foot section B as shown in Figure 1, so that the knees of the occupant may be elevated and he may rest in a sitting or somewhat inclined sitting position. The mechanism for such adjustment is similar to that shown and described in my companion application above referred to, and includes an operating shaft 46 journaled in the foot posts 12 just below the cross-bar 13, said shaft having projecting squared ends adapted to be engaged b a crank such as 31. Spools or drums 4 one at each side, are fixed to the llo lli

'j within the posts 12 and around direction. ulleys 49 pivoted therein (dotted vlines igure l), thence forwardly through the.-

adapted to be wound on said spools llor drums.

The cables 48 pass downwardly osts and over ulleys 50 suitably journaled eneath the si e rails 14. Struts 51 are fixed to and extend downwardly from end portions of the side bars 16, 17 of the seat section C, adjacent the joint between said section and the'foot section B, and each strut 51 carries on its lower end a grooved pulley 52, beneath which a cable 48 passes, the end of the cable then being fixed to an eye 53 carried by the side rail 14. Rotation of the shaft 46 in one direction causes the cables 48 to be wound on the drums or spools 47, thus applying upward pressure on the struts 51 through the pulleys 52 and thereby breaking the joints between the foot and seat sections and elevating the adjacent portions of said sections as shown. Ratchet and pawl devices similar to those shown in Fig-` ure 9 are employed for holding the shaft 46 and maintaining the adjustment when made. The side rails 14 and bed bottom carried thereby may be adjusted vertically of the posts 10, 12, to several different positions to suitrdifferent requirements, suchr as for normal use as a bed or for convenience in at` tending to obstetrical or other cases. Sockets 54 are carried by opposed faces of the posts 10 and 12 and are adapted to be engaged by tapered lugs 55 fixed to and projecting downwardly from end portions of the side rails 14. In this instance the sockets 54 are arranged at three different heights, providing for three selective vertical adjustments of the side rails and members carried thereby. (See Fig. 5.)

An arched frame 56 is adapted to be mounted on and attached to the bed at times said cross-bars. suitably journaled in the downwardly openfor the purpose of supporting body-suspending devices and operating mechanism.

The arched frame may be formed of channel bars with suitable braces 57 ,-the ends of the leg's of the arch resting on central portions of the cross-bars 11 and ,13 and being clamped thereto by bolts 58 extending through bar washers 59' mounted beneath An operating shaft 60 is -ing longitudinal member of the arched to' the; shaft 60 and a cable 66l is fixed to and adapted to be wound on es :h spool. A supporting barl 67 is suspended beneath the f arched frame 56,C by means about to be described, and extends substantially the length of the bed, said bar being provided with a number of cross-arms 68 secured at their centers thereto at spaced intervals throughout its length. The supporting bar 67 may c be of T-shape and the cross-arms of angle iron. Pulley blocks 69 are provided, each cable 66 passing beneath a pulley in one of said blocks'and then upwardly to points of attachment to cli s 7 0 swiveled on the shaft 60. The supporting bar 67 is sus ended by means of hooks 71 pivoted` to t e pulleyv blocks 69' and passingthrough holes kin the web .of said bar.v A hammock 72, formed of .canvas or other suitable material, is suspended from the cross-arms 68 by means of hooks 73` pivoted in end portions of the.

cross-arms and detachably engaging eyelets or the -like in side marins said hammock. In use the suspen ing device may be lowered by reverse rotavtion of the shaft 60 until the supporting bar 67 is in a position not far above the bed bottom. The canvas or hammock .'72 is detached and placed beneath the body of the patient occupying the bed; the hooks 73 are then engaged with the hammock and the shaft 60 is rotated in such manner as to wind the cables 66 on the spools l65, thus elevatingl the supporting bar and hammock,

and wit it the patient, to a suitable distance above the bed bottom to permit changing of bed clothing or the like, after which the patient may be lowered to the bed, the hammock detached from the supporting bar and removed from beneath the patient. The supporting devices may be held in elevated position by means of a pin 74 (Figure 4) lnserted between4 spokes of the gear 61 into a hole in the arched frame, said pin being attached to a chain 75 to reyent loss,

A standard 76, forme of a rod or the like and terminating in a hooked portion 77, is provided and is adapted to be mounted at any desired location on the cross-bars 1,1, 13 or side rails 14, for the purpose of supporting at an elevation relative to the bed a water bag or other receptacle employed in irrigating wounds, applying enemas or similar operations. To mount the standard 76 two clamp plates 78, 79 are provided, each terminating at, its lower end in a hook adapted to engage bene-ath the lower margin of a flange of one of the channeled mem'- bers (cross-bar or side rail), as shown in Fi re 8. The clamp plate 78 is straight anuplane above the hook l80 thereon land projects to a point above the member on which it is mounted, such as the side raila14. The other clamp plate, 79, is bent at right angles between its endsand extends across secured, as by welding, to one of the clamp plates in this instance to the flange 81 of the plate 79.

A weight attachment also is provided, by means of which a weight 83, suspended from a cord 84, may be applied 'to a portion of the v body of a patient in certain cases. The cord runs over a pulley 85 which is journaled cured by a clamping bolt 88.

between two plates 86, 87, substantiallyalike in shape, adapted to embrace a side rail or a cross-bar such as 13, their lower ends projecting below said member 13 and being se- 'lhe upper ends of the plates 8G, 87 are secured by a bolt 89, which may serve as a pivot for the pulley 85; and said plates preferably are A formed with a plurality of sets of alining -holes 90 so that the elevation of the pulley may be adjusted as desired, by selectively mounting thebolt 89 therein. The device is readily removed and replaced, and may be placed at any desired location on the cross-bars 11 and 13 or on either side rail 14.

Arched curtain rods 91 may be provided, one on each side of the bed frame, for the purpose of support-ing a curtain or mosquito nettlng over the bed. The rods 91 may be secured to the bed frame in any desired manner, as by inserting the ends thereof in holes in the osts or cross-bars of the frame.

I claim as my invention- 1. In a bed having spaced head and foot members, an arched frame adapted to span the space between said head and foot members and rest thereon, an operating shaft arranged longitudinally of and journaled in said arched. frame, a supporting -member consisting of an inverted T-bar extending longitudinally of said arched frame and adapted for vertical movement relative thereto, cables adapted to be wound on said shaft and attached at one end to the vertical flange of said Tbar, spaced cross-bars attached directly and rigidly to the horizontal member of said T-bar, and a hammock detachably suspended from said cross-bars.

2. In a bed having spaced head and foot members, an arched frame adapted to span the space between said head and foot members, said frame being formed of channel bars, the longitudinal member of which opens downwardly, a supporting member extending longitudinally of said arched frame and adapted for vertical movement relative thereto, an operating shaft journaled in the longitudinal member of said frame, spaced cross-bars carried bg said supporting bar, a hammock detacha ly connected to and suspended from said cross-bars, cables fixed to and adapted to be wound on said shaft Within the downwardly opening channel bar of said frame and extending downwardly and connected to said supporting bar, and means for rotating said shaft.
